Abstract

A device for determining an electrical wire bundle, in which, when the electrical wire bundle includes even one test electrical wire which conducts electricity to a terminal device, the electrical wire bundle is given an A-rating indicating an electrical wire bundle to be used for a test; when the electrical wire bundle includes at least one electrical wire which conducts electricity to the terminal device but is not the test electrical wire, the electrical wire bundle is given a B-rating indicating that the electrical wire bundle is not allowed to be disconnected; and when the electrical wire bundle includes only electrical wires that do not conduct electricity to the terminal device, the electrical wire bundle is given a C-rating indicating an electrical wire bundle not to be used for the test.

First claim

What is claimed is:

1. A system for producing and determining an electrical wire bundle that includes a test electrical wire to be used for an electrical test in a wiring structure interconnecting terminal devices through a plurality of wire harnesses each including a plurality of electrical wires composing an electrical wire bundle and connectors connected with the electrical wires, the device comprising:
a storage unit which stores connection information about connection relations between the electrical wires and the connectors; and
a processing unit which determines which electrical wire bundle includes the test electrical wire on the basis of the connection information stored in the storage unit, wherein,
the processing unit is configured to assign an A-rating to the electric wire bundle when the electrical wire bundle includes even one test electrical wire which conducts electricity to the terminal device,
the processing unit is configured to assign a C-rating to the electric wire bundle when the electrical wire bundle includes only the electrical wires that do not conduct electricity to the terminal device, and
the system is configured to produce a test wire harness including only the electric wire bundles having the A-rating, among the electric wire bundles having one of the A-rating and C-rating.

2. The system for producing and determining an electrical wire bundle according to claim 1 , wherein:
when the electrical wire bundle includes at least one electrical wire which conducts electricity to the terminal device but is not the test electrical wire, the processing unit assigns the electrical wire bundle a B-rating, and
the produced test wire harness further includes electrical wire bundles having the B-rating.

3. The system for producing and determining an electrical wire bundle according to claim 1 , wherein:
on the basis of identification information on pins of a test connector included in the terminal device used for the test, the processing unit is further configured to link pieces of the connection information stored in the storage unit to one another, and assign each of the linked electrical wires a category ‘a’ that indicates that the electrical wire is the test electrical wire, and
when the electrical wire bundle includes even one test electrical wire to which the category ‘a’ is assigned, the processing unit is further configured to assign the electrical wire bundle the A-rating.

4. The system for producing and determining an electrical wire bundle according to claim 2 , wherein:
on the basis of identification information on pins of a test connector included in the terminal device used for the test, the processing unit is further configured to link pieces of the connection information stored in the storage unit to one another, and assign each of the linked electrical wires a category ‘a’ that indicates that the electrical wire is the test electrical wire, and
when the electrical wire bundle includes even one test electrical wire to which the category ‘a’ is assigned, the processing unit is further configured to assign the electrical wire bundle the A-rating.

5. The system for producing and determining an electrical wire bundle according to claim 3 , wherein:
on the basis of identification information on pins which are pins of a connector mated with the terminal device used for the test and other than the pins of the test connector, the processing unit is further configured to link pieces of the connection information stored in the storage unit to one another, and assign each of the linked electrical wires a category ‘b’ that indicates that the electrical wire conducts electricity to the terminal device but is not the test electrical wire, and
when the electrical wire bundle includes no electrical wires to which the category ‘a’ is assigned but includes the electrical wire to which the category ‘b’ is assigned, the processing unit is further configured to assign the electrical wire bundle the B-rating.

6. The system for producing and determining an electrical wire bundle according to claim 4 , wherein:
on the basis of identification information on pins which are pins of a connector mated with the terminal device used for the test and other than the pins of the test connector, the processing unit is further configured to link pieces of the connection information stored in the storage unit to one another, and assign each of the linked electrical wires a category ‘b’ that indicates that the electrical wire conducts electricity to the terminal device but is not the test electrical wire, and
when the electrical wire bundle includes no electrical wires to which the category ‘a’ is given but includes the electrical wire to which the category ‘b’ is given, the processing unit is further configured to assign the electrical wire bundle the B-rating.

7. The system for producing and determining an electrical wire bundle according to claim 5 , wherein:
the processing unit is further configured to temporarily assign a category ‘c’, which indicates that the electrical wire or the connector does not conduct electricity to the terminal device, to all the electrical wires and connectors included in the connection information, and
for the electrical wires to which the category ‘a’ or the category ‘b’ is assigned, the processing unit is further configured to change the category ‘c’ to the category ‘a’ or the category ‘b’, and assign the C-rating to the electrical wire bundle that includes only the electrical wires of the unchanged category ‘c’.

8. The system for producing and determining an electrical wire bundle according to claim 6 , wherein:
the processing unit is further configured to temporarily assign a category ‘c’, which indicates that the electrical wire or the connector does not conduct electricity to the terminal device, to all the electrical wires and connectors included in the connection information, and
for the electrical wires to which the category ‘a’ or the category ‘b’ is assigned, the processing unit is further configured to change the category ‘c’ to the category ‘a’ or the category ‘b’, and assign the C-rating to the electrical wire bundle that includes only the electrical wires of the unchanged category ‘c’.

9. A method for producing and determining an electrical wire bundle that includes a test electrical wire to be used for an electrical test in a wiring structure interconnecting terminal devices through a plurality of wire harnesses each including a plurality of electrical wires composing an electrical wire bundle and connectors connected with the electrical wires, the method comprising steps of using the device according to claim 1 to perform:
storing connection information about connection relations between the electrical wires and the connectors;
determining which electrical wire bundle includes the test electrical wire on the basis of the connection information stored in the storage unit, wherein the determining step comprises:
assigning an A-rating to the electric wire bundle when the electrical wire bundle includes even one test electrical wire which conducts electricity to the terminal device; and
assigning a C-rating to the electric wire bundle when the electrical wire bundle includes only the electrical wires that do not conduct electricity to the terminal device; and
